Should I buy a HDTV?

[BroadcastTVnot]

I only watch movies on my ten year old 25" RCA TV. So far the local video rental store has very few Blu Ray movies -- maybe a dozen. I assume Block Buster would have more, but I haven't looked since the video store I go to is cheaper at $1 a week for an older movie. I don't get broadcast TV reception at my house because of being located in the mountains, and don't want to spend the big bucks for a satellite subscription right now; so basically, I just watch standard DVD movies on my ten year old RCA TV.

I would like to get a bigger screen TV that has surround sound. However, would it be worth buying an expensive HDTV with so little HD programming? I want to put the TV into a big, very bright family room and was thinking of a 40/46" HDTV. I like the Samsungs, but need a matte-non-glare screen probably a 630. The Sonys are OK but more expensive. I could buy a smaller, cheaper set now - perhaps 32" - wait a year or so to buy a bigger set and move to the small HD set to another room. Of course, the cheapest alternative is to wait until I have more access to HD programming.

So, would it be worth to upgrade cost to watch non-HD movies.
